PRlNTERS PROOF-PRESS.

SPECIFICATION forming part of Letters Patent No. 608,813, dated August9, 1898.

Application filed December 27, 1895. Serial No. 573,456. (No model.)

T0 all whom it may concern:

Be it known that I, FERDINAND WnsEL, a citizen of the United States,residing at New York, (Brooklyn,) in the county of Kings and` State ofNew York, have invented certain new and useful Improvements in PrintersProof- Presses, of which the following is a specification.

This invention relates te that class of printing-presses known asproof-presses, which are used in newspaper and other oices for takingproofs from forms of Vvarious widths, said press being arranged forfeeding several independent webs of paper of a width corresponding tothe forms set up; and the invention relates more especially to certainimprovements in the printers proof-press for which Letters Patent were4granted to me heretofore, No. 537,658, dated April 16, 1895, wherebythe press is better adapted for newspaper-work, as it enables thesimultaneous proof-taking of several forms of different widths and sizesand the feeding of independent webs of paper to the same, the ends ofsaid webs bein g held by a suitable gripping device above the formswhile the impressionroller is moved back over the forms and rcleasedagain when the impression-roller is moved forward over the forms fortaking proof.

The invention consists of a proof-press for newspaper and other printingoffices which comprises a feed mechanism by which the ends of the websof paper are fed for a short distance after the proof-printed sheet istorn off, a gripping device for holding the ends of said webs inposition without interfering with the form during the backward motion ofthe impression-roller, and of means by which the gripping mechanism isreleased when the impression-roller is moved in forward direction fortaking proof.

The invention consists, further, of a printcrs proof-press in which theshaft of the paper-feeding rolls is provided with fixed and withadjustable and indepcndently-movable core pieces and an independentsleeve or sleeves also provided with fixed and adjustable core-piecesfor supplying several webs of paper of varying width to the forms, aswill be .fully described hereinafter and finally pointed out in theclaims..

parts in Fig. 3.

In the accompanying drawings, Figure l represents a side elevation of myimproved printers proof-press, in which the carriage is shown as-havingreached the end of its 'forward movement, while the sliding cams areshown as shifted. Fig. 2 is a plan view of the same, partly inhorizontal section, on line 2 2, Fig. l. Fig. 3 is a detail perspectiveView of the mechanism for holdin-g, gripping, and releasing the web orwebs of paper for taking proef, drawn on a larger scale. Fig.

3 is a sectional view of the gripping mechanism corresponding to theposition of the Figs. 4 and fl and 5 and 5 show, respectively, detailside views and vertical sections of the gripping mechanism in itssuccessive positions; and Figs. 6, 7, and 8 are respectively a detailplan view, a vertical longitudinal section, and a vertical transversesection on line 8 S, Fig. 7, of the rollsupporting shaft Awith twodifferent cores for the paper-rolls.

Similar letters of reference indicate corresponding parts.

Referring te the drawings, A represents the supporting-frame of myimproved proof-press for newspaper and other printing offices. Thesupporting-frame is composed of upright standards@ o, which "are bracedby longitudinal and transverse tie-reds. On the standards is supported abed-plate B,which is provided at each side with guide-rails b b, onwhich a reciprocating carriage O is guided. Motion is imparted to thereciprocating carriage@ b v means of a transverse shaft D, having acrank-handle D', which shaft carries an impression-roller F, to each endof which are applied gear-wheels d, that mesh with fixed racks d',supported at both sides of the bed-plate B. By turning the crank D inone or the other direction the carriage C is moved forward or backwardover the bedplate B. At one end of the carriage C, supported in inclinedbearings c, are two inkingrollers E E, which are in contact with aninktransferring roller E', the shaft of which turns in bearings of theframe of the carriage. The roller F.v receives ink by means ofintermediate rollersc c from a suitable ink-fountain E2, that isarranged above the intermediate rollers, as shown in Fig. 1. A.transverse shaft G is su orted in bearings at the u s PD D IOO

per ends of upright standards G at one end of the frame of the carriageC, said shaft carryin g a plurality of rolls of paper,whieh move withthe carriage C over the bed-plate B. The webs of paper pass from therolls over suitable rollers g g, of which roller g is a mereguide-roller, while roller g is a friction or pressure roller, saidrollers bein g supported in the slotted arm of an oscillating frame g2,the pivot-shaft of which extends from one side of the frame of thecarriage to the other. The supporting-frame g2 of the rollers g g isprovided with forwardly-extendin g arms g3 on both sides, said armscarrying antifrictionrollers g4, which move over the guide-rails ZJ andover auxiliary rails r at both sides of the bed-plate and which servefor the purpose of oscillating the frame g2 when passing onto the railsr, so as to move the friction-roller g' into contact with theimpression-cylinder F for the purpose of drawing the webs of paper inthe opposite direction to the motion of the carriage when the carriageis arriving at the end of its forward motion. This feature is shown inmy previous patent referred to, but its function and operation will bemore fully described in detail hereinafter. At the opposite side of theimpression-cylinder F the frame of the carriage is provided with abending and cutting device I, which is composed of a cutting-blade t',that is sharpened at its lower edge and attached at its upper edge to atransverse bar Z', that is pivoted to the carriage C. A bending-bar Z2is attached to the knife-blade t' and extended below the sharpcned edgeof the same, the lower end of said bending-bar being rounded off, so asto press the paper into a groove 715 on the raised end portion of thebed-plate, as shown in Fig. 3, To the transverse bar 7l' is alsoattached an arm or finger i3, by which the motion of the cutting-bladeand bending-bar in one direction is produced. To one end of thetransverse bar z" is attached one end of a helical spring i, the otherend of which is attached to a fixed point on the carriage, so that whenit is not set to tension the spring will hold the cutting-blade and thebending-bar in inclined position adjacent to the impression-roller F, asshown in Fig. 5, When the carriage C arrives at the end of its forwardmotion, the linger abuts against the raised end portion of the bed-plateand moves thereby thecutting-blade andthe bending-bar against thetension of the spring Z into vertical position, as shown in Fig. 3, sothat the bendingbar clamps the web or webs of paper firmly into thegroove Z5 in the bed-plate, while the cutting-blade permits the tearingoff by the attendant of the proof taken during the forward motion of thecarriage. As soon as the carriage commences its return motion thecontact of the finger with the end portion of the bed-plate isdiscontinued and the cuttingblade and bending-bar are returned again bythe action of the spring 'Z4 into their former inclined position, asshown in Fig. 5,

The carriage C is provided at its opposite sides with sliding cams L,which are provided at their under side, below the shaft of theimpression-cylinder, with inclined cleats Z, that are retained inposition by suitable setscrews Z. On the upper side of the sliding lcamsL are arranged inclined upwardly-extending lugs Z2. The cleats Z rest oneccentrics Z3, which are mounted on the verticallymovable standards C ofthe carriage, and can be raised or lowered by suitable handles, as isshown in my said patent, especially in Fig. (i thereof. The sliding camsL are guided on the eccentrics Z3 and on suitable lugs Z4 on the frameof the carriage and are operated in connection with stops ss on thebed-plate of the carriage, the stops s at left end of the bed-platebeing arranged in lon gitudinal slots i s2 of the guide-rails b Z,whereby they can be adjusted and the motion of the carriage C limited asrequired by the length of the proofs to be taken. The shaft of theimpression-cyll inder is journaled in bearings ofupright standards O,which are guided in vertical ways of the carriage C and engaged at theirlower ends by the free ends of springs Z5, lwhich are applied at theiropposite ends to the lower part of the carriage C, as shown in g Fig. l,the tension of said springs tending to .'fpress the standards C inupward direction ,and the eccentrics Z3 against the cleats Zof thesliding cams L. The tension ofthe springs 5 Z5 can be adjusted bytension-screws Z, turn l1 ing in lugs of the carriage C.

The carriage C is provided with antifriction-rollers C2, that rest onthe sliding cams f L and facilitate the shifting of the same when i theyarrive in contact with either stop s ors', the journals of said rollerspassing through fslots in said standard, as in my patent referred to.These rollers C2 also retain the slidl ing cams in position againstupward displace- L ment, so that said sliding cams may force `the 5eccentrics Z3 and theimpression-cylinderF in downward direction againstthe motion of the 5 springs Z5 and into position for printing. The shortauxiliary rails r, arranged at one end of 4the rails Z), are beveled attheir inner ends and guided on stationary headed pins r2. The lsaidrails r carry upwardly-projecting pins 1 r3, which are each adapted tobe engaged on l one side by a projection r4 on the carriage C and on theother side by the beveled nose rs on the end of the spring-finger r6.The beveled ends of the rails r permit the rollers g4 y. of the frame g2to pass freely onto the rails 'r when the carriage C is near the end ofits forward motion, whereby the frame g2 is oscilflated and thefriction-roller g of the same brought in contact with the impression-roller F, as shown in Fig. 3f. As soon as the im- 5pression-roller leaves the form the printed proof would be drawn overthe form or else torn unless the friction roller g is brought f againstthe impression-roller F. Thereby an 5 additional length of paper isfcd,corresponding to the distance between the end of the IOO IIO

- forni and the extreme limit of forward mothe clamp i2 and blade i.

tion, due to the fact that the friction-roller g is positively driven byreason of its pressing the paper web against the impression-roller.

During the backward motion the paper must be fed in the oppositedirection until the end of the web is about to be released by Otherwiseanobjectionable loop would be formed under the impression-cylinder. Thisfeed of the web is secured by keeping the roller g' in contact with theimpression-cylinder a short time after the return of the carriage iscommenced, which operation is accomplishedl as follows: Vhen thecarriage is nearing the end of its forward movement and the rollers g4rise up on the ends of the auxiliary rails r, the pins r3 are engaged bythe )rejections r4 on the' carriage, which causes t e rails to be pushedforward, with the said rollers still on the end of the rails, until theforward movement of the carriage is completed. By this construction therollers g4 are permitted to leave the rails r very soon after the returnmovement is commenced. After the rollers g4 leave the rails r the innersides of the noses ri engage pins rsand move the rails back to theirformer position. The inner sides of the noses r5 are beveled to such anextent as that they can they do not prevent their snapping over and pastthe pins as the carriage is being moved back. On the other hand, theouter sides of the noses are so much beveled as that during the forwardmovement of the carriage l they slip over and past the pins withoutacting on the rails. As the eXtra length of paper below theimpression-roller would be in the way of the same during the returnmotion of the carriage, it is necessary to retain each web of paper bythe gripping device, which device is formed by the cutting-blade c' anda bent gripping-finger m. (Shown in Fig. 3.) The gripping device holdsthe end of each web of paper in raised position above the form or forms,so as to permit the return of the carriage over the form without anytearing or rumpling up of the paper. ln order that the gripper may clampthe end of the web onto the blade fr', as hereinafter described,it isnecessary that the end of the web be projected a short distance past theedge of the blade. This is accomplishedA by releasing the roller gslightly before the end of the web is released by the blade, whereby aslight loop is formed under the impressionroller, which loop straightensout, due to the sti ['tness of the paper, and the end of the web springspast the edge of the blade when released thereby. When the carriagearrives at the end of its backward motion, the gripping device isreleased and the paper fed during the forward motion of the carriage tothe impression-roller and forms. As'soon as the impression-rollerarrives over the form durA ing its forward motion the paper is heldthere by down upon the form and an impression` carriage over the forms."ward motion ofv thel carriage the inking-roll ers pass over the fermahead of the impresact on the pins r3 to move the rails back; but

Itaken. The paper being thus held between the impression-roller and theform, the same is fed automatically to the latter as the earriage movesalong. When the carriage arrives at the end of its forward motion, asshown in Fig. l, the impression-roller F is lifted by the shiftingof thesliding cams L, caused by their contact with the end stops s', theshifting motion bringingthe cleats Zover the eceentrics Z3.Simultaneously the journal-bearin gs of the inking-rollers E E ride upon the inclined lugs of the sliding cams L, so that the rollers E E arethereby bodily lifted over the form. The impression-roller and theinking-rollers being thus lifted are then moved with the carriage inbackward direcp tion over the form without coming in contact therewithuntil the carriage arrives at the opposite end of the bed-plate, whenthe opposite ends of the sliding cams L form contact vwith the stops sat that end, so as to shift the sliding cams L and move the cleats Zback over the eccentrics Z3, whereby the impression-roller as well asthe inking-rollers are` returned into their former lower position andare then moved by the forward motion of the During the forsion-rollersand supply the ink required for v' printing the proofs, while theimpressionlength of paper for taking the proofs.

I OCl As it is necessary in newspaper offices toV `take proofs fromforms of various widths vvided with one or more fixed cores G2 and withone or more adjustable cores G, so as to provide for the exact width ofeach web to be used. The cores G2 G3 of one of the rolls of paper areattached directly to shaft G2, so that the same turns with the paperwhile it is fed to the impression-roller in taking proof. The cores G2G3 of the other rolls are applied to independent sleeves G4, placedloosely on the shaft G', so that these rolls can turn independently ofthe shaft G and supply the webs to the impression-roller and forms whentaking proofs of additional forms placed on the bed- The arrangement ofan independent sleeve G4 on the shaft G is clearly shown in by whichmyimproved proof-press is better heretofore patented by me.

It is obvious that a gripping device has to be arranged for each webseparately.' The gripping devices are shown in plan viewin Fig. 2 and intheir different successive posi- 'lhey are applied to a crankedtransverse shaftt, which yis supported on the standards G of the earfriage Cback of the impression-roller F. To Ethe outer end of the crankedshaft `Z is keyed ITS `Figs. 7 and 8 and forms one of the features ashort arm t' and adjacent and approximately at right angles thereto acam t2, as shown in Fig. 3. A helical spring t3 is attached at one endto the shaft t and at the other end to the 5 standard G, said springexerting a motion in downward direction on the cranked portion of theshaft t. Below the arm t and in contact therewith is arranged aslide-piece t1, which is guided in ways of a bracket 155, at- Io tachedto the standard G. The lower end of the slide-piece t4 rests on theconcaved wider portion t7 of an elbow-piece t6, the upper end of whichis keyed to the outer end of the bar t. Adjacent to the elbow-piece isloosely applied to the bar t" a lever t8, which is located in the planeof the cam 152 and concaved at its upper end. The lower end of the levert@ is slotted and connected with a fixed pin t9 on thc inner end of thesliding cam L, as shown in zo Fig.3. The parts described-namely, the armt', the cam t2, the slide-piece t4, the elbow-piece t, and the levert8-serve, in connection with the shaft t, bar i,'and the sliding cam L,to impart the required motion to the gripping 2 5 devices, so as to setthem into the required positions for gripping` and releasing the ends ofthe webs at the proper time.

When the carriage arrives at the end of its forward motion, the slidingcams L are shifted 3oand the impression-roller and inking-rollersraised, as before described. Simultaneously therewith the arm i3 abutsagainst the end portion of the bed-plate and moves the cutting-blade andbending-bar down, so as to 3 5 press the web firmly on the bed-plate, asshown in Figs. 3 and G. The proof-printed portion of the web is thentorn off along the cutting-blade by the operator. Vhen theimpression-cylinderleaves the type,the frame 4o of the friction-rollerg' is oscillated by the rollers g4 moving over the rails r, and the saidroller g is placed in contact with the impression-roller. The contact ofthe arm 3 with the bed-plate imparts an axial turning motion to the barz" and a lifting motion to the elbow-piece t6, which latter raises theslidepiece t4, the latter again lifting the arm t and turning thecranked shaft z5 against the tension of its spring t3, as shown in Fig.3. The

wise raised, so that the proof-printed web can be torn off without beinginterfered with by the finger m. sliding cam L moves the upper end ofthe os- 5 5 cillating lever t8 away from the cam t2, as shown in Fig. 3.The operator then turns the crank D so as to move the carriage inbackward direction over the form. On the return motion of the carriagethe finger 3 is 6o released and the bar with the cutting-blade andbending-bar, returned by its spring fi into its normal position. Theelbow t is moved in downward direction with the bar t", which motion isimmediately followed by the slide-piece t, arm and shaft z5, which areunder the influence of the spring t3, so as to place the parts into theposition The shifting motion of the i shown in Fig. 4. Simultaneouslytherewith the lower end of the web is moved out, as be- `fore described,for a short distance beyond l the edge of the cutting-blade in themanner previously described. The grippingfinger m, being moved indownward direction by the F turning of the shaft t, takes up the end ofthe web and presses it against the edge of the cutz ting-blade, so as tofirmly grip the same, asshown in Fig. 4, and holds it thus gripped`until the carriage arrives at the end of its backward motion. Thesliding cams L, be-

i ing shifted by the stop s at the opposite end of the bed-plate,produce the lowering of the impression-roller and inking-rollers/asbefore described, and simultaneously therewith the [oscillation of thelever t8, and thereby bythe i action of its upper end on the cam t2 theturn- Eing of the shaftt against the tension of its spring t3, thelifting of the gripping-finger m,

and the releasing of the web, as shown in Figs. 5 and 5a. The operatorthen reverses l the motion of the crank D and moves the carriage forwardover the form, so as to take the next proof, as before described. Whenthe ping of the web by the latter and the descendl ing gripping-finger,as before described.

By placing several forms on the bed-plate yand arranging a correspondingnumber of rolls of paper on the shaft G several proofs can be taken atthe same time, the widths of fthe rolls corresponding to thewidths ofthe 1 forms, while all the webs are simultaneously gripped during thereturn motion of the carriage, so as not to interfere in the least with'the forms during the return motion of the g impression-roller over thesame, and released at the beginning of the forward motion, so as not tointerfere with the proper printing of the proofs by the press.
